I was looking at paint and primers for my truck (it's getting pretty confusing with all the options out there). I came across a historical paint chip library at DuPont. The link is DuPont Historical Color Chip Library I haven't found the color chips for Mack trucks yet, but did find the colors for a Coca-Cola truck! Let me know if you find the right pages for our old Mack trucks, and better yet, post them! Scott

Hi Rob, Yep, no whining, but the growling has started! The snow got me off guard this year, I normally have the old dog in the shop out of the elements. Not that it's any warmer in there, but at least it would have been dry. Best for you and yours this holiday season! Scott

got us a bit of snow and artic cold here in Washington State, but this dog ain't whining! Although my lab sure tucks her tail when it's time to head out! Have a safe one, Scott

Anybody up for a BMT Wiki topic to post these?

Joe, You aren't out much trying to pull injectors and giving her a liberal dosing of PB or ATF over a week or two. My 4-71 has evidence of a rather large pipe wrench on the crankshaft snout/harmonic balancer (too dark to look tonight). Ease in to it, think about how far you are going when you start turning bolts, and let your knowledge guide you rather than emotion (sounds like I've been there, huh?)! Might pull the oil pan drain plug for a couple seconds & see what comes out (I know I'm crossing my fingers for oil)... Best of luck, it will turn out. Scott

Rob and Thermodyne, Both very good points made. My impression so far has been along with Rob's statements; 100% of the air is filtered (to a point/size). But then again, Thermodyne makes a good point with longevity with an oil bath. I have seen too many pieces of new equipment, technology, CAD designing down to the gnat's a$$, that it just can't hold a candle to the old stuff. Guess that is why we are all here with our passion for Mack trucks. But with everything else the same, as Rob says, "Of course I'm assuming good maintenance practices" is the key to long life of equipment and early detection of problems. Scott

Rob, Thanks for the information on flywheels and bellhousings - good stuff to know. The genset I have has an oil bath filter on the intake, but not much of a muffler on the exhaust. With all this, it is loud, but I'm thinking with a decent muffler it would be toned down to a decent level. Has anybody looked at efficiencies of an oil bath vs. a paper media intake filter? How about engine longevity between the two? I have my impressions, but want to see what other people think. Thanks, Scott

Where are you located? Try trucktrader.com to get some ideas of pricing, etc. What is your price range? You will be better off financially to put your capital outlay into the initial purchase rather than buy a fixer that takes a substantial amount of time to get rolling and cost at least twice what you think it will to get it running & reliable! Good luck in your search. Scott P.S. Post some pictures of your EH, join the EH vin list posting, and park it the "garage"!

Couple of nice looking rides you have there, Jim. You'll have to talk with Larry (aka Freightrain) as he pulls his racecar & trailer with a B61. Welcome to the board, I'm sure you will find many knowledgeable and helpful people that can answer almost any question. Scott

Dang it guys, You got the juices flowing, I started looking around for a donor crewcab pickup to put my 4-71 generator set engine into!!! Thermodyne B63, do you have torque numbers for each of the engines (I would suppose they would vary widely based on injectors and vintage)? Rob, as the resident board generator expert, not sure what style of flywheel would be on a getset...much less if it is a standard bellhousing (would assume so, but you never know). Any ideas on transmissions that would handle horsepower & torque (mine is a 1940's non-turbo version), number of gears/speeds needed to avoid huge rpm changes per shift, and if an Allison AT540 or MT653(?) would be a good idea? Thanks, Scott

Robert, I'll see if I can put my excel spreadsheet into words... If you want to get speed in miles per hour, MPH; 1. start with this: rpm (revs per minute) * 60 (minutes per hour) gives engine revolutions per hour 2. then this: tire diameter (inches) *3.14159 => this gives the tire circumference 3. divide the tire circumference by: 12 (inches per foot) * 5280 (feet per mile) => gives the tire circumference in miles instead of inches! 4. now multiply the transmission ratio by the differential ratio (engine rev / driveline rev * driveline rev / wheel rev) multiply items 1 and 2 together, then divide by items 3 & 4; For your truck, this becomes: MPH=(2100rpm*60)*(43.1*3.14159) / (12*5280*5.77*0.85) = 55mph. Not your 60mph quite cruising speed, but pretty respectable. I know I don't want to hit 70mph in my old dumptruck! Just for grins, I looked at gearing and torque. Assuming an ENDT673 puts out 600 ft-lbs, your low end gearing of 18.96, your tire size (I assumed 43.1"), and good traction, you can put 6334 pounds of force to the ground! That's almost 800 pounds of force per tire from 1422ft-lbs of torque applied to each tire! OK, enough is enough, the geek engineer in me is starting to come out! Hope you have fun with your truck!
